I had added a new commit after running npm run test-and-fix and the PR is not reflecting the commit here. Its stuck in "Processing Updates" states since then. (Probably about 2 hrs now)

@psx95 yeah, sorry about that, we're having some issues with CI right now it seems.

[psx95]

@cartermp Looks like the CI issue is resolved, kindly take a look 😃

Thanks!

Hey @psx95, the CI is passing, but it looks like you might have inadvertently updated a localized page in this PR. Could you remove the ja file changes? Thanks!

[psx95]

Hi @tiffany76,
I reverted the requested changes, thanks for the review!
